The 30 second leak calculator

Salon, barbershop, nails, tattoo studio, clinic. If you live off a booking diary, two sliders will give you a rough, honest number.

Average appointment price £32

Your typical ticket, not your dearest one.

Missed slots in a typical week 6

No-shows, late cancellations nobody refills, gaps nobody notices. Most owners guess low.

Weeks you trade a year 48

Holidays off, real life included.

Could be leaking out of your diary

£9,216

That is £192 a week, £768 a month, before a single new client walks in.

And this is only the empty slots. Clients who quietly stopped coming back sit on top of this number.

That was a guess. Want your real number, free?

Pop your details in and I will work it out from six totals off your own booking dashboard. No export, no client list. Results back within two working days.

Worked out from six totals you already have. Works alongside Fresha, Treatwell, Square, Booksy, Slick and more. Plain code, never sent to an AI. Nothing to install.
